Benchmark 5000-6000 Boiler Installation & Startup Manual
SECTION 2: INSTALLATION
NOTE:
Benchmark 5000 and 6000 units may be installed with zero side clearances in pairs only.
The perimeter clearances still apply (see Figure 2-2 and the drawings in Appendix A:
Dimensional Drawings).
IMPORTANT!
Ensure that adequate clearance exists at the rear of the unit to permit installation and service
maintenance of the AERCO Condensate Trap. Refer to Section 2.8 for Condensate Trap
installation details.
When using the AERCO Condensate Neutralizer Tank for condensate drainage, the tank
must be installed in a pit, OR the boiler and AERCO Condensate Trap must be elevated
higher than 4" (10.2 cm) above the floor. See Condensate Neutralizer Tank Instructions TID-
0074 for details.
